the -t'elloe of thewheel to prevent its surreptitious detachment.

With these and other objects in view, the 'invention consists in certainnovel tfeatures of construction as hereinafter shown and described andthen specifically pointed out in the claim, and in the drawingsillustrative oi' the preferred embodiment of the invention.

a demountable rim, andfthe tire of a' wheel, with the improvementapplied, and partly in section.

Figure 2 is a. transverse section on the line 2--2 ot Figure 1, lookingin the direction ofthe arrow.

Figure 3 is a plan view of the lock portion of the device. I l

Figure 4 is a sectional detail illustrating the improved device appliedto a Wheel havinga hollow or channel shaped elloe.

rihe improved device may be adapted without material structural changeto any of the various construction of wheeis, in which deniountable rimsare employed, and with fello'esof various forms, but for the purpose otillustration is shown applied to convenn tional forms of suchstructures', in which 1G represents the cross section oit an ordinarywood fclloe, 11 thecross sect-ion ot a conve tional demonntablerim,111'the elloe band, 112 the clamping ring, 11s the washer, and 1'14 oneof the clamp clips, these parts being of the usual construction.

The improved device includes a bolt 14 extending through the elloe andthreaded into the rim 11.

Bearing upon the inner face of the felloe 10 or 23 is a substantiallyclip shaped shell or socket 16 open at the outer end. The

outer terminal ot the stock 14 is preferably Jformed with a square headas shown at 17 in Figure of the drawing to receive a socle etwrenchinserted through the outer end of the shell, butmay lformed inconical Figure 1 is a transversesection of a felice,

shape and slotted to receive a screw driven, as shown at 17 in Figure 1.The shell is formed with a small stud or spur 16 to enter the elloe 10or 23 and operative'to hold lthe shell from rotation relative to thefel- A dust cap-18 is applied to the shell 16, to protect the latter andits contents, from dust, mud and the elements.

' Formed on the interior ofthe shell 16 is an annular flange 19, asshown. The bolt 14e being threaded into the rim may be detached and therim released by inserting a suitable turning implement through the openouter side ofthe shell.

ATo prevent the bolt 14 from being thus released byunauthorized persons,a. lock device is provided to be inserted in the shell, this lock deviceincluding a casing or shell 20 having oppositeiy directed bolts 21adapted to be projected over the lia-nge 19, as shown in Figure 1, by asuitable key inserted through a key hole indicated at 22.

The specific construction of the loc-k device is not shown, as it formsno part of the. present invention. v

s The device isgapplied before the tire is placed in position andinflated, and after this is done, the rim cannot be detached uniess thestock be first released, and. this can be accomplished only by releasingthe lock by a person in possession ot the key.

TWhen employed in connection with a channel shaped felloe as shown inFigure s, a clamp nut 2e will preferably be employed.

The improved device is simple in construel tion` can be inexpensivelymanufactured, ei tective in operation, and protects the rim fromsurreptitious detachment.

The preferred embodiment of the invent? tion is disclosed in thedrawings and .forth in the specification, but it will be un derstoodthat modifications within the scope ot the claimed invention may be madein the construction Without departing 'from the principle of theinvention or sacrificing any of its advantages. v

Havingthus described the invention whatv is claimed is The combinationwith a fastener having :1 head, of a cup shaped element surroundareduced portion passing through said ing the head and having an internalannular nular flange and adapted. to engage bene-ath flange spaced fromits free endA a lug formed the same, and a removable cover cap thread-10 on the element and adapted t0 engage' a `ed over and enclosing theelement.
